    Headlamp wiring question (67S USA)

    Now that the wiring is installed, I'm almost finished 'proving it out'…connecting, testing and such. Using a L59 diagram (which I believe is non-USA), it shows the high-beam lamps getting power from fuses 11 and 12 via white wires. (along with the high-beam indicator lamp-white/blu). When I jump power to these terminals, I get nothing at the headlamps, although the indicator lamp is lit. Do the high beam wires go directly from the fuse panel to the lights, or do they go somewhere else first, like fog lamp relay or something? Any help, thanks

    Thanks for reply:
    Looking at both diagrams, I see no difference, and I see no "fog lamp" relay in either. Knowing that USA fog lamps go out when hi-beams are energized, I suspect that may be part of my issue.
    Tomorrow I will energize and trace my white wires and see where they lead. Thanks again
